Entirely different. New students would have to make loan payments for 20-25 years before they could even
potentially qualify for loan forgiveness. It's not the same as a universal tax credit.
Other student loan forgiveness programs have already existed and began under republicans:

College enrollment has not increased since Biden expanded loan forgiveness, and is not predicted to.
Radicalization mostly occurs at elite universities which very few are able to attend. Outside of that, this left-wing bias is mostly cultural, in the sense that there is strong acceptance of LGBT, etc. However, it is not academic. For example, I've never seen an economics class with a left-wing bias.
Of course, there are elective courses everywhere that might be seen as left-biased. However, elective (ie optional) goes against the definition of indoctrination.
